Problem 2: For the beam given below: (a) Calculate all support reactions. (b) Draw the shear diagram. Show all important values of shear. Show the sign convention within each region. (c) Draw the moment diagram. Show all important values of moment. Show the sign conventions within each region (concavity: smiley face, sad face, etc.) (d) Sketch the deflected shape. Show supports in your sketch. For your solution, let w = 2 kips/ft and L = 20 ft. A L 22 B L W C

The horizontal beam is supported by a pin at A and the pin-connected link BC. It has a uniformly distributed loading w = 7.0 kN/m as shown in the figure. All the pins are in double shear and have a diameter of 20 mm. Determine the max shear stress in the pin at A. Input your answer as a value only in MPa to one decimal place without +/- sign. W 1.5 m 2 m B 1 m

The two bars are made of polystyrene, which has the stress-strain diagram shown. If the cross-sectional area of bar AB is 975 mm² and BC is 2600 mm², determine the largest force P that can be supported before any member ruptures. Assume that buckling does not occur.

I need help with this exercise from my homework. I have no idea about how to solve it. I need an step by step solving and explanation, please.

Identify the equation for the deflection at point C.

Question stated in the picture. Detailed answer is needed

The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that are welded to a rectangular web plate. Dimensions of the cross section are: h = 470 mm tw = 14 mm d = 120 mm t = 9.6 mm Additionally: • The area of each pipe is A = 3330 mm2. • The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 428040000 mm4. If the beam will be subjected to a shear force of V = 225 kN, determine the shear stress at point H, located at yH = 110 mm above the z centroidal axis.
